Machines need to be calibrated regularly so these will be able function properly. A licensed engineer or mechanic is the only one qualified to perform such tests and the length of time it takes to inspect one unit could take hours depending on how complex or sophisticated it is.
If the machines being checked are in large factory such as one that produces cars, teams are dispatched to conduct the calibration. In most cases, this is done every six months. The only difference is that the people who will do this will go to the plant unlike a car owner who will have to drive the vehicle to the shop.
Is there any difference between a machine and a car when it comes to calibration? Yes in terms of the instruments used to conduct such tests.
Large ones like those in the factory have to be dismantled and hand held instruments such as frequency counters, multimeters, network analyzers, oscilloscopes, power supplies, spectrum analyzers and RF power meters are used throughout the tests.
Automobiles on the other hand are tested using computers and some similar instruments that will be finished much faster than those in the factory so the owner can drive off when this is done.
If a problem has been found, the specialist will recommend that the machine should not be used first until a replacement part has arrived. But in minor cases, a simple adjustment will do the trick making it up and running again.
But the use of calibration instruments is not only done in factories. These are also done in laboratories to make sure the machines used are able to perform to what it was designed to do.
The National Institute of Standards and Technology is responsible for setting the regulations making this all possible. After all, safety begins by those who are designing the prototype until the new product is launched into the market. This will ensure that defects can be avoided and recalls are not necessary since this will cost the company a lot of money.
Anything that uses machines will have to be calibrated at one point or another to ensure these are performing well as though these were good as new. The plant may have a crew to do this or a contractor can be called in to perform such services which is really up to those in charge of keeping the place running.
